‘They look cold and ghostly enough even in broad daylight,’ said Ethel, as they pushed on along a broad smooth track of emerald green, one of several green belts that varied the dull purple of the sea of heather. Overhead, on tireless wing, the hawk wheeled. The lapwing, with complaining note, skirred the plain, striving with world-old artifice of drooping wing and broken flight, to lure away the human intruders from her flat nest, full of speckled eggs. The moorland hare, dark-furred and long-limbed, broke abruptly from her seat and galloped off unpursued. The Circles were reached at last, and proved to be quaint rings of dilapidated buildings, all of unhewn stone and of the rudest construction. Here and there the huts, roof and walls alike composed of rough slabs, were intact. Nothing could be more desolate than the appearance of these bare, gaunt hovels, reared by the hands of the long dead, standing solitary in the midst of a desert. ‘Here they lived once upon a time, those old people, the heathen miners, whose bronze tools and lumps of ore and morsels of charred wood are even now sometimes picked up by boys who hunt for birds’ eggs on the moor. They worked near the surface, and never drove their galleries very deep into the earth. And then came Christian times, when these hovels were inhabited by very different dwellers, until at last the mines were given up as no longer worth the labour of winning the tin.’ Ethel looked around her with a kind of awe. She had imagination enough to enable her to realise the dim Past, when these deserted huts were peopled by inhabitants strange of garb and speech, gnomes of the mine utterly unlike to any who now tread English ground. In fancy she could behold the motley throng of Pagan toilers, whose bronze picks had once rung against gneiss and granite, mica and sandstone, on the now silent moor. There the Briton, his fair skin stained with woad, and the small and swarthy mountaineer whose forefathers had preceded the Celt in ownership of the land, had laboured side by side with Spaniard, Moor, and Goth, with Scythian, Arab, and Indian—slaves all, and mostly captives in war, whom the cruel policy of Rome consigned to far-off regions of the earth, much as our justice stocked Virginian plantations and Australian cattle-runs with the offscourings of ignorance and crime. It was at the grave as it were of a dead industry that Ethel now stood. The ground, honeycombed by what resembled gigantic rabbit-burrows, was strewed here and there with dross and scoriæ, and blackened by fire, wherever the remains of a rude kiln told of smelting carried on long ago.
